Tennis ball
From Biocrawler, the free encyclopedia.
A tennis ball is a hollow rubber ball that is used primarily in tennis but is used in other ways. It is usually spherical, light (weight about 57 g), brightly coloured and has 2 white curved shapes as part of the design.
Even though, as the name suggests, the ball is used primarily in tennis, it can be used as a safe substitute for games where a solid ball is necessary, for example, to replace a cricket ball, which can inflict damage or injury if not used correctly.
The gift of tennis balls offered to Henry in Shakespeare's Henry V is portrayed as the final insult which re-ignites the Hundred Years War between England and France.
- When we have match'd our rackets to these balls,
- We will, in France, by God's grace, play a set
